Review summary

Summarized from anonymous rental reviews on Openigloo.

Recent tenant feedback for buildings managed by Ariel Grunberg reveals significant dissatisfaction with ownership and management responsiveness. While the location and neighbors generally receive positive remarks, numerous renters report poor maintenance, persistent plumbing and ventilation problems, and neglected building updates such as elevators. Garbage management and pest control efforts appear inconsistent, and noise levels are frequently described as disruptive due to insufficient soundproofing. Management staff, including specific individuals, face criticism for unprofessional and disrespectful behavior. Overall, tenants advise improved communication, respect, and infrastructure investment to enhance tenant experience under current management.

Reviews

Former tenant·2 months ago

Ownership & Management are evil

Pros

Neighbors are lovely! A lot of long-time residents.

Cons

- The real estate agent Amanda, and her husband (and building manager?) Dakota are evil. They verbally abuse the staff and don't give a shit about residents... they are selfish, entitled little weasels. - When they updated the elevator they didn't do anything to accommodate the pregnant, elderly, or injured - except for put trash cans and chairs that became trash cans on every floor. -Prior to the elevator getting fixed, they didn't give two shits about maintaining it. - Market rate, but totally overpriced for the experience of living there.

Advice to the owners

Replace Dakota and Amanda. They suck and no one in the building likes them.

Looks better than it is

Pros

Great location and neighborhood

Cons

Aside from the lobby which is designed to attract new tenants, the building is poorly maintained.

Advice to the owners

Why can't you do better? It's exploitative.
